In a saucepan dissolve the sugar with the cream and baking soda over
medium heat, stirring constantly. Bring mixture to a boil and stop
stirring. Continue to boil the mixture until it makes a thick syrup that
forms a ball when dropped into cold water (firm ball stage).

Remove the pan from the heat and add the butter,
orange peel, nuts and a pinch of salt.. Beat the mixture well until it
becomes quite thick.

Pour fudge onto a buttered plate and when cold cut it
into 1-inch squares. or drop teaspoons of the fudge on to a large
buttered platter.
